Hydrokinetic Construction (torque Absorption)
The Froude waterbrake is based on hydrokinetic construction or (torque absorption).
The machine consists of an impeller (rotor) which accelerates water outwards by its rotation. The water has its velocity changed by a stator which causes the water to be returned to the inner diameter of the rotor. For given mass of water, this velocity change yields a corresponding momentum change – and the rate of change of momentum is proportional to a force. This force acting at some point within the rotor and stator is a distance from the shaft centerline, and a force multiplied by a distance produces torque.
